Subject: [PATCH 32/34] brcmfmac: common: Add support for downloading TxCap blobs
Date: Mon, 27 Dec 2021 00:36:22 +0900 [thread overview]
Message-ID: <20211226153624.162281-33-marcan@marcan.st> (raw)
In-Reply-To: <20211226153624.162281-1-marcan@marcan.st>
The TxCap blobs are additional data blobs used on Apple devices, and
are uploaded analogously to CLM blobs. Add core support for doing this.
Signed-off-by: Hector Martin <marcan@marcan.st>
